CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 439,897, dated November 4, 1890.

. Application filed June 26, 1890. Serial No. 356,762. (No model.)

Toall whom it may concern:

Be it known that I, PERCY W. ROSS, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Car-Couplings, of which the following is a specification.

The object of my invention is to provide simple and efficient automatic means for securing or locking car-coupling links or other car-coupling devices.

The accompanying drawings illustrate my invention.

Figure 1 is a top or plan view of a drawhead provided with my improvement. Fig. 2 is an endview of the same with latch removed. Fig. 3 shows a section on line 00 0c of Fig. 1.

My invention relates particularly to the combination of parts hereinafter set forth and claimed.

The pin is formed of a main shaft a and a forwardly-projecting blade I), narrower than the shaft and provided at its front lower cor ner with a downwardly-proj ecting anteriorlybeveled locking-arm O. The draw-head is provided above the chamber B with a vertical pin-hole e, corresponding in cross section to the cross-section of the main body of such pin, and provided below such chamber with a hole corresponding in cross-section to the cross-section of the shaft a of the pin, which extends below the locking-arm c. The top of the pin is provided with a perforated lug d, to which can be secured a chain or other means for lifting the pin to uncouple.

In Fig. 1 D is the locking bolt, tumbler, or latch pivoted in the draw-head and having the posteriorly-beveled hook or arm E, with which the locking-arm c engages.

In practice, when it is desired to couple the cars, the pin is allowed to remain in its normally-depressed position (shown in Fig. 1) and the couplings are brought together.

It will be understood that the couplings on both cars are duplicates and are reversed in their positions relatively because of their positions on reverse ends of their respective cars. The .opposed draw-heads engage. re spectively, with the tumblers D, thus forcing each tumbler respectively toward the drawhead to which it is pivoted.

In the coupling shown in Fig. 1 the hookE is made to engage the beveled face of the arm 0 when the tumbler D is thrown into its transverse locking position, thus first raising the pin to allow the hook to pass, and then the pin will fall into its looking or depressed position, as shown in Fig. 3.

The front walls h of the pin-hole form a bearing for the pin to resist the strain when the train is being drawn.

The shaft a is designed to project below the draw-head and may be provided with a key 11 to preventwithdrawal.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the pin set forth, formed of a main shaft and a forwardly-projecting blade narrower than the shaft and provided at its front lower corner with a down- Wardly-proj ecting anteriorly-beveled lockingarm, the draw-head provided above its chamber with a vertical piu-hole corresponding in cross-section to the cross-section of the main body of such pin, and provided below such chamber with a hole corresponding in crosssection to the cross-section of the shaft of the pin, and the tumbler pivoted in the drawhead and having the posteriOrly-beveled hook, substantially as set forth.
